Description of Down Hole Drilling HDD Drill Rod With Even
Composition And High Purity
Each of drill pipe is treated by shot peening. After shot peening
treatment, surface of drill pipe and thread gets residual pressure
stress. This stress can improve drill pipe anti-fatigue service
life. Shot peening treatment on thread can help thread compound
adhering to thread. Thread service life is improved.
Non destructive test is performed according to NDT standard Level 2
with combination of eddy and ultrasonic to guarantee material
quality without any defect.
Surface of the threads will be cleaned to remove burr adhered after
threads are opened.
Afterwards, the tread surface will be phosphated to improve surface
conditions.

Product Application
HDD drill pipe is a tool applicable for transferring torque and
tension of drillers in the process of directional drilling
construction. Due to the fact that it has to bear torsion, tension,
bending, friction and vibration in the process of directional
construction, the requirements for processing process are very
strict.
Heat treatment control:
Heat treatment will greatly improve the material strength and
increase the thread wear life of the rods and casings. We conduct
either tru-wall or both ends heat treatment to the tube body. After
heat treatment, strength, hardness, straightness and concentricity
of the treated tubes will be tested in our lab.
Thread opening process:
Accuracy of threads will determine the use effects and life time of
drill rod and casings.
CNC latches and form cutter are used in thread opening processing
to minimize error made by anthropic factors.
Product Advantages:
strong and ductile steel pipe;
solid quality and considerate service;
cost-effective;
